In 22th century, mankind has left the Earth. A new space epoch began, called the Isis era. Human beings built an oasis in deep space, a space station called LaGrange Point. From there, they could send expeditions to remote planets and to explore the space. You control a young pilot named Jin. One day, when you descend into LaGrange from your space ship, you are attacked by mysterious robotic invaders. Your task is now to travel through space and to find out the cause of the assault. But you don't even suspect you'll soon be involved in a deep mystery that was destined long time ago..."LaGrange Point" is one of the few old-school console-style RPGs to be set in a science fiction environment and to feature space flights. The combat system requires you to use special points (called BP) in order to perform simple attacks, cast spells, and use various techniques that will cost you your HP. You fight random monsters and bosses in turn-based combat viewed from first-person perspective, like in Phantasy Star series.
